part of a water-cleaning process in which small sticky particles clump together to make larger and heavier particles (floc). The larger particles eventually sink to the bottom of a containment area and can then be removed.

Chemical processes where salt causes the aggregation of minute clay particles into larger masses that are too heavy to remain suspended water.

The clumping together of smaller particles to form larger particals which drop out more quickly. The flocculence of yeast is of interest to brewers. Different yeasts exhibit different degrees of flocculence.

IS THE YEAST GATHERING TOGETHER AND SETTLING OUT OF SUSPENSION

The tendency of a yeast strain to clump together and precipitate from solution, thereby clarifying the beer or wine. Ability to flocculate is an important quality of yeasts used for brewing and winemaking (as opposed to baking yeasts). Traditional methods developed in the Champagne region of France require flocculant yeast strains which settle in the neck of the overturned bottles, where they may be removed before the wine is sold. Highly flocculant strains may produce stuck fermentations if temperatures dip below the recommended level. See also, Attenuation.

a treatment process usually done before sedimentation. It involves the addition of flocculants and coagulants (chemicals) to form large particles (aggregates) from the fine solids suspended in water so they can settle quickly or be filtered faster.

The clumping together of clay suspended in river water into bunches that are large enough to settle out.

The clumping, gathering or fallout of yeast cells after fermentation. Different yeast strains have different levels of flocculation.

Joining together of particles in suspension.

Growing together of minute particles to form larger ones which are called floc and are easier to filter. Also referred to as coagulation.

reverses the processes that cause dispersion of soil by causing finer particles to clump together into larger units or ‘flocs’ that can settle in a reasonable time or can be filtered. Flocculation is usually carried out in ponds or tanks with the most commonly used flocculation agents being gypsum or alum.

Name given to the process of coalescence and settling of yeast cells into a firm deposit.

Flocculation is the brewing term for a yeast's propensity to cling together and 'settle out' of your beer. Highly flocculent yeast will settle out of a beer quickly after fermentation while less flocculent strains will not clear as quickly.

Particle aggregation in dispersions as a result of decreased colloid stability. Flocculation can be controlled and therefore can help to control paint rheology.

The combination, agglomeration, aggregation or coagulation of suspended particles in such a way that they form small clumps or tufts (called floc).

The change which takes place when the dispersed phase of a colloid forms a series of discrete particles which are capable of settling out from the dispersion medium.This is an almost inevitable result of its mixing with a solution containing electrolytes e.g. Seawater

in water treatment, the slow mixing process in which particles that have had their charge neutralized (coagulation) are encouraged to clump together with other particles, creating larger masses that will settle more rapidly.

Part of the water treatment process.

large scale treatment process involving gentle stirring whereby small particles in flocs are collected into larger particles so their weight causes them to settle to the bottom of the treatment tank.

The clumping together of protein molecules or yeast cells to form relatively large, irregularly shaped particles.

The bridging of flocculant chemicals between agglomerated particles for larger settleable flocs.

The process in which small particles in water are made to coagulate (clump together) and form a precipitate. It is done by adding a FLOCCULATING AGENT such as aluminium sulphate or iron (III) sulphate.

Is the process of agglomerating particles into larger masses called flocs, which then settle down to the bottom by gravity.
